In Summary

Wireless and remotely accessible Emotion Detection Technology can sense the hidden emotions of individuals without even looking at them.

Editor Posted by Tripti

Understanding human Emotions is an intricately complicated subject and the correct assessment of emotions of an individual is often perplexing. Several times we fall short of predicting the emotions of an audience or patients especially those who experience mental problems. Emotion Detection Technology can be used as an aid to understanding the emotions of an individual by studying various physiological parameters.

Wireless Emotion Detection Technology

The conventional emotion detector is an extensive state of the art facility with a highly complicated instrumentation. In order to understand the emotions of an individual, a lot of wires needs to be connected to the body, which limits its widespread real time applicability.

A new and advanced EQ-Radio method of emotion detection was developed by MIT researchers. It employs radio signals, which when reflected off a person, analyzes the breathing pattern and heart rate of that particular person. Physiological changes in breathing and heart rate are the chief indicators of fear, anger, happiness, sadness and other emotions. The physiological parameters can be recorded in a remote device and can be further analysed by values into a standardisedmachine learning algorithm. The results obtained from the calculations ca help in predicting the emotion of the person.


The EQ-radio employs the frequency modulated carrier wave predator technique, which is equipped for high precision human body tracking. It can even track the vibrations in the chest muscles as a results of breathing. It can thus differentiate changes in pattern of breathing.

EQ-Radion in Clinical Psychology

Depression is a major psychological problem which affects more than 50% of the population. In some cases it has more severe consequences than others. In such cases, having an instrument, which can remotely assess the mood and emotion of the patient and can help in making a clinical assessment of the condition is highly advantageous.

Currently, the only way of assessment in the testimony of the patient himself. Getting a second source of clinical information will be highly useful in deciding the pattern and duration of treatment.

Part of “smart homes”

With the increasing demand of tech savvy instruments, cars and homes, engineers have started integrating novel electronic devices to enhance its appeal and comfort. The EQ-Radio Emotion Detection Technology can be integrated into smart homes, so that they can automatically change music and light settings along with changing mood.

Real time feedback

It technology can also help filmmakers and artists to get instantaneous and real-time feedback from audiences to improve artistic performance

The real-time applications of the technique is still under debate.Scientists are yet to standardize the instrument, only after which the instrument will be granted permission to be used for real-time clinical or non-clinical applications.
